Hot days call for a tankini top that can pull double duty as a gorgeous shirt and this one is up to the job. The high neck and back provides the full coverage you want while offering solid protection from the sun with the help of Upf 50 fabric that prevents burns. If you wear one size on top and another on bottom it can be easily paired with whatever fits you best whether it's a separate pair of board shorts with a pocket for your keys bikini bottoms or a swim skirt with a matching trim. Anything and everything will look cute! The soft stretchy fabric won't sag after a few laps either.
